FIG. 1.
Schematic representation of the gag and pol regions of HIV-1 (top) and the amino acid sequences of portions of p6Gag protein and viral protease encoded by two different reading frames (bottom). The amino acid residues conserved in >98% of the majority HIV-1 substrains (group M), which include subtypes A, B, C, D, F, G, H, and J and circulating recombinant forms (AE, AG, AGI, and AB) (HIV Sequence Database [http://hiv-web.lanl.gov]), are shown in large capital letters. The B subtype consensus sequences are shown in small capital letters. The nucleotide sequence of our interest is shown in open letters. PR, protease; RH, RNase H; INT, integrase.
